Perfect Thrillers Collection

A perfect daughter. A perfect monster. When Anna and David adopt twelve-year-old Mia, it feels like their family is finally complete. She's polite, intelligent, and eager to please-everything they'd hoped for. But when Mia's behavior toward Anna turns cold and unsettling while remaining perfect for David, cracks begin to show. Small accidents around the house, strange conversations, and moments that don't add up leave Anna questioning her own sanity. As the tension builds, she realizes that bringing Mia into their home wasn't just a mistake-it might destroy their family forever.

Be careful who you trust with your child. After losing her husband, Sarah is doing everything she can to hold herself-and her young son Theo-together. When Elena appears, calm, capable, and eager to help, she seems like the answer to Sarah's prayers. Theo adores her, and for the first time in months, Sarah feels like she can finally breathe. But soon, little things start to feel… off. Lullabies Sarah has never sung filling the house. Documents moved. Unfamiliar items appearing in Theo's room. And the way Elena looks at her son-as if he belongs to her. As Sarah digs deeper, she realizes this perfect nanny isn't who she claims to be. And letting Elena into their home might not have just been a mistake-it could cost Sarah everything.
